Leonard Snart: My, my, my. Getting rather violent in your young age.
Barry Allen: Yeah, what were you doing?
Leonard Snart: [uncuffs himself] Magic.
Cisco Ramon: The Montgomery 3000.
H.R. Wells: Wait, is that bad?
Cisco Ramon: Well, we're looking at a 25-ton door that can withstand a 30-megaton nuclear blast. And aside from being bombproof, the Montgomery 3000 can only be unlocked by a voice recognition system necessitating from three different pass codes from three different people as if that weren't enough, the thing costs $10 million to build.
Leonard Snart: [unlocks the door] 37 seconds. I must be out of practice.
Barry Allen: Well, A.R.G.U.S. should ask for their money back.
Leonard Snart: Wait! Make the plan, execute the plan.
[King Shark slams on the door]
Barry Allen: Expect the plan to go off the rails.
Leonard Snart: Who is Grodd?
Barry Allen: Telepathic gorilla. Spared his life on another Earth so he could invade Central City. It's what mercy gets you.
[seeing cells for Cheetah and Cupid]
Barry Allen: This must be where Waller kept her Suicide Squad.
Killer Frost: We're a team, right? Barry and Caitlin, at it again.
Savitar: You're not Caitlin. And I'm not Barry.
Leonard Snart: My guess is the power source is most likely here.
Joe West: Why there?
Leonard Snart: Because it's the deepest part of the facility. And if it's as valuable as you say it is, then the deepest recesses of any facility are usually the most secure.
Cisco Ramon: Hmm. Smart, Snart.
Cisco Ramon: Smart, Snart.
[seeing no one else is laughing, he awkwardly turns to leave]
Cisco Ramon: I'm gonna keep hacking away and find out for sure.
Barry Allen: Do you have any idea what else might be down there?
Leonard Snart: Doesn't matter. There are only four rules you need to remember: make the plan, execute the plan, expect the plan to go off the rails, throw away the plan. Follow my lead and you'll be fine.
Barry Allen: Give me your cold gun.
Leonard Snart: So you can do what, exactly?
Barry Allen: Snart, there's only one way that tech's getting out of here.
Leonard Snart: Oh, I see. You didn't just recruit me for my skills as a thief, did you? You wanted a partner who wouldn't mind if you got all murdery.
Barry Allen: I told you what I'm up against. All right? Give me the gun.
[Snart hands his gun over and Barry powers it up]
Barry Allen: Open the door. Open the door!
Leonard Snart: Have you seen "Shark Week", Barry? Me, I can't get enough of it. Good thing the Waverider has cable.
Barry Allen: What's your point?
Leonard Snart: Most sharks are cold-blooded. But the great white shark, like our friend in there, is partially warm-blooded.
Barry Allen: He's susceptible to cold.
Leonard Snart: Never strays under water colder than 53.6 degrees Fahrenheit. If we lower the temperature in that room to 53.5 degrees, King Shark should fall asleep like a little baby. Or you can go ahead and kill him and prove what a badass you are. Your choice.
Leonard Snart: [after knocking out King Shark] Reminds me of "Jaws". They didn't show the shark because they couldn't afford to make it look good.
[as they make their way into the room, King Shark's dorsal fin rises out of the cold mist; after a tense moment, it sinks back down]
Barry Allen: How long do you think he'll stay asleep?
Leonard Snart: I like "Shark Week". I'm not a marine biologist.
Leonard Snart: Seen a lot of things, but a half-man, half-shark takes the cake.
Barry Allen: I can't believe A.R.G.U.S. turned King Shark into a guard dog.
Leonard Snart: King Shark. That's adorable.
Savitar: What I remember... is being created as a disposable life. Something to be... thrown away when Barry Allen was done with me. He didn't care about me. Why should I care about his love?
Leonard Snart: Barry Allen, hero of Central City. This is Siberia in the year 1892. We're a little out of your jurisdiction.
Barry Allen: Hear me out. I wanna recruit you for a mission.
Leonard Snart: I'm already helping a bunch of idiot do-gooders. Sorry, I'm up to my fuzzy hood in teamwork.
Barry Allen: Would it help if I said please?
Leonard Snart: No. You already have a bunch of superhero types in your life. Why ask me?
Barry Allen: Well, you have a... particular set of skills.
Leonard Snart: Great movie. Last time we tried to be buddy-buddy, it didn't work out so well... for you. Why trust me now?
Leonard Snart: Spit it out, or I'm gonna step on that ship and pretend like this conversation never happened.
Barry Allen: Iris.
Leonard Snart: Oy. The girlfriend.
Barry Allen: Fiancee.
Leonard Snart: Mazel tov. What about her?
Barry Allen: If you don't help me, she's gonna die.
Leonard Snart: True love? That's your pitch?
Barry Allen: It's all I've got.
Leonard Snart: I assume saving your girlfriend requires us to do something less than lawful.
Barry Allen: We need to break into A.R.G.U.S. and steal an alien power source.
Leonard Snart: The Flash a thief. That's my kinda mission. One condition: my rules.
Barry Allen: Your rules.
